摘要:
Depiction, within a single imaging modality, of an intervention device and body tissue surrounding the device, is improved by interrogating a subject that includes the intervention device and the tissue. An image is created using,for a parameter, a value, of the parameter (160), better suited to one or the other of a device region depicting the intervention device and a tissue region depicting the tissue. The value is used to yield respectively either a first image (152) or a second image (154). Respective presets may correspondingly have different values for the parameter. From jointly the first image and the second image which are both of the single modality, a combination is formed that is an image of the intervention device depicted as surrounded by the tissue. The combinations may be formed dynamically and ongoingly. An apparatus for the improved depiction may be configured for the use of the parameter in a stage prior to image processing conducted on a scan-converted image (146) if such image processing is employed.
摘要:
The present invention relates to a method for providing a three-dimensional ultrasound image of a volume (50) and an ultrasound imaging system (10). In particular, the current invention applies to live three-dimensional imaging. To improve three-dimensional ultrasound imaging of a large volume, it is contemplated to adjust the central receive frequency(70) of a bandpass filter (35) of a signal processor (34) as a function of a spacing (60) of scanning lines (59) of a transducer array (26).
